Triangles: Types and Similarity
100
This is a line that runs along the edge of a circle.
What is a chord?
100
This mathematical figure has no shape or size, and is represented by a dot and a letter.
What is a point?
100
This is the written form of the midpoint formula.
What is (x₁ + x₂)/2 , (y₁ +y₂)/2?
100
These two angles add up to 180°.
What are supplementary angles?
100
This is what you would use when you know that two triangles share two similar sides.
What is SSS?
200
This is a line that connects a circle at two different points.
What is a secant?
200
This mathematical figure extends out in all four cardinal directions.
What is a plane?
200
This is the written form of the distance formula.
What is √(x₂ - x₁)² + (y₂ - y₁)² ?
200
These two angles are directly across from each other when two lines intersect.
What are vertical angles?
200
This is not a valid strategy to prove two triangles similar.
What is AAA?
300
If the diameter of a circle is 17, then this is the circumference.
What is 53.41?
300
This is what you would call two points on the same line.
What is colinear?
300
Two endpoints of a line have the coordinates (1, -3) and (4, 5). This is the midpoint.
What is (2.5, 1)?
300
These three angles in a triangle add up to 180°.
What are interior angles of a triangle.
300
This vocabulary is key to figuring out whether two triangles are similar.
What is a ratio?
400
If the radius of a circle is 6, then this is the area. (Round to the nearest tenth.)
What is 113.1?
400
This is a part of a line that has one endpoint.
What is a ray?
400
The midpoint coordinates of a line are 4, 9. One of the end coordinates is (3 , 10). This is the coordinate pair of the other.
What is (5, 8)?
400
This is what you would call angles 4 and 5, depicted in this diagram.
What are alternate interior angles?
400
∆EFG ~ ∆EXY. Side FG = 12, Side XY = 36, and Side EF = 8. This is the value of side FX.
What is 24?
500
The angle measurement of a section of a circle is 70° and the arc length of that section is 48 in. This is the diameter. Round to the nearest hundredth.
What is 246.86?
500
Two sides of a quadrilateral, the top side and left side, would be defined as this.
What is perpendicular?
500
This is the distance between (8, 7) and (0, 1).
What is 10 units?
500
This is what you would call angles 1 and 7, as depicted.
What are alternate exterior angles?
500
∆ABC ~ ∆ADE. Side AB = 6, Side BC = 2, and Side BD = 4. This is the value of Side DE.
What is 10/3?
